Abstract

A method and equipment manufacturing predetermined low bark content wood chips and a high bark content fuel fraction from wood chips with bark attached, includes mechanical bark removal treatment, in which the bark is removed from the chips and their size is reduced; pre-cleaning of the flow of chips with bark attached, into a flow of chips with a bark content of less than 10% and high bark content rejects, with the aid of pneumatic and mechanical sieving; final cleaning of the aforesaid wood chip flow from the pre-cleaning, with the aid of an optical separator, to create low bark content wood chips and a fraction with a higher bark content; collection of the rejects leaving the process, to create the aforementioned high bark content fuel fraction; and seiving out of the flow of wood chips, before the mechanical bark removal process, a predetermined thin fraction of the chips, which bypasses the debarking process.
